In cases where the shape of the bolt is complex or when the bolt is fixed and cannot be removed!
We would like to introduce a processing case from Sansei Industrial Co., Ltd. We applied pre-coating processing with SG-2451J to the nut. It is usually easier to apply pre-coating processing to bolts and male threads than to nuts, but in cases where the bolt shape is complex or the bolt is fixed and cannot be removed, we perform pre-coating processing on the nut and threaded side. This work is more labor-intensive compared to processing on bolts and threads, but our company can carry out manual work by skilled workers while keeping costs down. 【Features】 ■ Pre-coating processing on the nut and threaded side ■ Possible to carry out manual work by skilled workers at reduced costs *For more details, please refer to the PDF document or feel free to contact us.

Company information
Sansei Industrial Co., Ltd. is a company located in Anjo City, Aichi Prefecture, that specializes in resin coating processing and pre-coating processing (bond loosening prevention processing). The resin coating processing uses powdered resin and employs the fluid immersion method, which is the most widely used for substrates such as metal and glass. This results in a finish that is uniform and glossy. In pre-coating processing, a high-strength epoxy resin-based adhesive is used, which primarily consists of epoxy resin encapsulated in microcapsules. Fastening with screws and bolts is an essential technology for any industrial product. The use of pre-coated bolts improves the quality of fastening.
